ppc64le - TestClosestEdgeQueryTrueDistanceLessThanChordAngleDistance failure due to floating point precision differences

I ran tests on ppc64le using "go test -v ./..." command.

The TestClosestEdgeQueryTrueDistanceLessThanChordAngleDistance fails due to floating point precision differences:

=== RUN   TestClosestEdgeQueryTrueDistanceLessThanChordAngleDistance
